鲁班山南矿风量增加后通风阻力变化分析与对策

Analysis and Countermeasures of Ventilation Resistance Change after Air Quantity Increase in Lubanshan South Mine

鲁班山南矿目前为高瓦斯矿井,随着14采区和深部煤层的开采,该矿将按煤与瓦斯突出矿井管理,随之而来的是矿井风量将从现在的8400～8530m^3/min增加到13000m^3/min左右.通过通风网络解算,分析了该矿风量增加后风阻的变化,以及风量增加后带来的风速超限等问题,并提出针对该矿实际的解决方法和建议.最后还提出了一个值得商榷的问题.

Lubanshan South Mine is a gassy mine, with the development of No. 14 mining district and the extraction of the deep coal seams, the mine will be managed according to the standard of coal and gas outburst mine, and for this reason, the air quantity of the mine will increase from 8 400~8 530 m3/min to about 13 000 m3/min. In this paper, analysis was carried out on the change of ventilation resistance and the problem of wind speed overrun after the increase of the mine air quantity through the ventilation calculation, and some corresponding solutions and suggestions were proposed. Finally, a question being worth discussing was put forward.
